SAD-IRON HEATER.

Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed. July 29, 1907. Serial No. 385,963.

To all whom it may concern:

Be it known that I, GEORGE H. GREGORY, a citizen of the United States, residing-in the city of New York, borough of Manhattan, in the county and State of New York, have in vented a certain new and useful Improvement in Sad-Iron Heaters, of which the following is a specification.

The invention relates to heaters of the Bunsen burner type, and the object of the invention is to provide a heater for sad irons of the usual forms, which shall be inexpensive in construction and economical in gas consumption, and in which thebody of the iron will be efficiently and uniformly heated while the handle remains at a comparatively low temperature and conveniently presented to the operator.

The invention consists in certain novel features of form and arrangement and details of construction, by which the above objects are attained, to be hereinafter described.

The accompanying drawings form a part of this specification and show preferred forms of the invention.

Figure 1 is a side elevation of the heater with an iron in position therein, the cover being shown in vertical section. Fig. 2 is a corresponding plan view, the iron and cover being indicated by dotted lines. Fig. 3 is an end view partly in vertical section. The plane of section is on the line 83 in Fig. 1. Fig. 4 is a side elevation of a portion and shows a modification in the means for attaching the heater to a table.

Similar letters of reference indicate like parts in all the figures.

The heater comprises a bifurcated support, the arms of which extend horizontally and separated to receive between them the handle of an inverted sad iron the body of which rests on the arms or branches, and means for supplying heat to the body, preferably by the combustion of air and gas escaping through .orifices in the branches.

The heater is preferably of cast iron and has a tubular mixing-chamber A equipped with an air controlling shutter B therefor, and an adjustable gas regulator B with its nipple B for the reception of a flexible gas connection, not shown, all of which may be of any ordinary or approved construction.

From the mixing-chamber extend two parallel tubular arms or branches A A plugged at their outer ends and preferably beveled slightly on the upper portions of their adjacent surfaces, the bevel continuing from one to the other of the branches at their junction, as shown. Along this plane face a number of gas delivery orifices a a are produced through which the mingled gas and air from the mixing-chamber escapes and is burned to From the outer sides of the branches ex- I tend brackets A A serving to support a cover 0 of sheet ironor other suitable material inclosing the body of the sad iron and confining the heat thereto. The cover is open below and has openings 0 c in the upper portion to permit products of combustion to esca e.

Tie heater may be supported by various means; in Fig. 1 is shown a clamp A cast in one with the mixing-chamber A and extending downwardly therefrom, equipped with a clamping-screw D by which the heater may be detachably secured to the margin of a table, ironing-board orthe like. In Fig. 4 the heater is represented as supported on legs A cast thereon, and which may be attached to a table by screws extending through the feet A.

The iron is introduced in the inverted position with the handle lying in the space between the branches and preferably with the heel of the iron toward the junction of the branches at which portion a greater number of orifices a a are provided for the purpose of projecting a greater volume of flame against this heavier portion of the iron. The cover is then applied to confine the heat to the body of the iron. The latter is removed for service by removing the cover, grasping the comparatively cool handle and withdrawing it from the branches; a second iron being substituted to be used when the first has cooled.

Although I have described the invention as intended for heating sad irons, it will be understood that it will serve successfully as a heater for cooking utensils and other purposes. Such may be placed on the cover while an iron is being heated, or a third iron may be thus partially warmed preparatory to its introduction into the heater.

Gas or analogous inflammable vapors may be supplied otherwise than through the interior of the branches, or may be supplied through one alone, the other serving merely to support the iron.

The bifurcated construction shown presents the body of the iron directly to the jets of fiame and thus heats it economically and uniformly and tends to avoid heating the handle, and the space between the branches provides a central draft for the burner permitting ample supplies of oxygen to reach the jets, thus insuring complete combustion and the elimination of disagreeable odors.

1. In a heater of the character set forth, a bifurcated support having its branches separated to receive between them the handle of an inverted sad iron supported on said branches, and means for sup lying heat to the exterior of said iron wiile thus supported.

2. In a heater of the character set forth, .a

' bifurcated support having hollow branches separated to receive between them the handle of an inverted sad iron supported on said branches, said branches having gas delivery orifices therein, and means for supplying gas to the interior of said branches.

3. A sad iron heater comprising a mixingchamber, means for supplying air and gas thereto, and tubular branches extending from said mixing-chamber and arranged to receive between them the handle of an inverted sad iron supported on said branches, the latter having gas delivery orifices therein.

4. A sad iron heater comprising a mixingchamber, means for supplying air and gas thereto, tubular branches extending from said mixing-chamber and arranged to receive between them the handle of an inverted sad iron, said branches having gas delivery orifices, and lugs on said branches for supporting the body of said sad iron above said branches and exposed to jets from said orifices.

5. A sad iron heater comprising a mixingchamber, means for supplying air and gas thereto, tubular branches extending from said mixing-chamber and arranged to receive between them the handle of an inverted sad iron supported on said branches, laterally extending arms on the latter, and a cover supported on said arms to inclose the body of said iron.

6. A sad iron heater comprising a mixingchamber, means for supplying air and gas thereto, tubular branches extending from said mixing-chamber and arranged to receive between them the handle of an inverted sad iron supported on said branches, the adjacent faces of said branches beveled on their upper portions, and having gas delivery orifices in said beveled faces.

7. A bifurcated support for a sad iron, havmg its branches arranged to receive be-.

tween them the handle of an inverted sad iron supported on said branches, means for supplying heat to the body of said iron, and means for detachably securing said support to a table or the like.

8. A sad iron heater comprising a mixingchamber, means for supplying air and gas thereto, tubular branches extending longitudinally therefrom and parallel with each other, arranged to receive between them the handle of an inverted sad'iron supported on said branches, the latter having gas delivery orifices, and a clamp on the under face of said mixing-chamber, whereby said heater is detachably secured to a table or the like.

9. A sad iron heater comprising a mixingchamber, adjustable means for supplying. air and gas thereto, tubular branches extending longitudinally from said mixingchamber and arranged to receive between them the handle of a sad iron supported in an inverted'position on said branches, the latter having gas delivery orifices, a clamp on said mixing-chamber whereby said heater is detachably secured to a table or the like, laterally extending arms on said branches, and a cover supported by said arms to inclose the body of said iron.

In testimony that I claim the invention above set forth I affix my signature, in presence of two witnesses.
